I noticed this last week before I was leaving for vacation, but the problem is persisting. I have this issue whether at home or in the office. Regular or private browsing mode. The OGS app on my phone still works, but is less than ideal for live games.
I am connecting from the east coast US if that makes any difference.
I took a screenshot of the issue with the Chrome dev console open approx. 15 minutes ago and there has been no change.
